1 SAFETY INFORMATION
This device complies to current applicable safety standards. Installation, maintenance and use of
this actuator will have to be done by skilled and trained staff only.
Please read carefully the whole document prior to mounting and starting-up.
2 ASSEMBLY
Actuator should be secured directly to the valve using proper bolts or via a proper interface.
After assembly, the actuator can operate in any position. However, cable glands should not be
oriented upwards (loss of water tightness) and the motor will preferably not be positioned at the
bottom (potential internal condensation trap)
Note 1 : Do not handle the actuator by handwheel, it could damage the gearworm.
Note 2 : If the actuator was delivered mounted on the valve, the basic settings should have been done.
Note 3 : see §.7 for details on storage precaution prior to starting-up.
3 HANDWHEEL OPERATION AND DECLUTCHING
In general, the handwheel does not turn during electrical operation. Even if turning, the solid
handwheel does not have any protruding part and therefore does not present any risk of any kind
for the operator. Moreover, for the actuators with the highest torque, the torque limit system
brings an additional level of protection.
EZ4 to EZ15 models:
These actuators are equipped with a manually declutchable handwheel.
To operate manually the actuator, turn while pulling the handwheel
in order to mechanically engage it.
To declutch the handwheel, just push it back towards the actuator
body.
EZ100 to EZ1000 models:
These actuators are provided with an automatic declutching hand-
wheel, with motor drive priority. In order to operate manually the
actuator, turn the arrow of the handwheel clutch button in front of the
triangular sign on the housing (it might be necessary to turn the hand-
wheel by a few degrees to release the claws). When the motor starts,
it returns automatically into declutched position.
EZ60 models:
These actuators are equipped with declutchable intermediate gears. By moving the clutch lever, the
motor is physically disengaged from the gears. Once the manual handwheel operation has been
completed, do not forget to clutch the motor back. Otherwise, once started-up, it would run and heat
up until the motor thermal protection switch closes. If repeated, these conditions can generate a motor
breakdown .

4.1
ELECTRICAL CONNECTIONS AND PRELIMINARY TESTS
All components of the actuator are wired to a common
terminal strip. Remove the cover and pass the cables through the cable
glands (M20). Refer to the wiring diagram for details on the terminals
numbering system.
Both thermal protector and torque limit switches must be integrated into
your control system (see wiring examples) in order to prevent potential
damage to the actuator or valve.
The following points must be checked:
a) Make sure that power supply voltage is in accordance with the data engraved on the actuator
nameplate
b) Check that all cable glands are correctly tightened,
c) Move the valve manually to an half-open position,
d) Operate an electrical opening and check that the motor rotates in the right direction. Press
manually on the «OPEN» travel limit switch ; the motor should stop.
In the same way, check that the closing electrical command as well as the «CLOSED» travel
limit switch are working correctly,
e) All models except EZ4 to EZ15 : Operate an electrical opening. Press manually on the «OPEN» torque
limit switch ; the motor should stop. In the same way, operate an electrical closing check that
the «CLOSED» torque limit switch is working correctly,
If any misfunction was detected at this stage, please check the overall wiring.
For safer working conditions, we recommend that the power supply now be switched off especially
if the actuator output max. torque exceeds 300 N.m.
4.2
SETTING OF MECHANICAL STOPS AND TRAVEL LIMIT SWITCHES
Mechanical stops description and function :
These items avoid any over-travelling during handwheel operations.
The stops can be positioned either on the actuator itself or on the 1/4 Turn
worm gearbox if any.
Actuators and gears are supplied and tested for a 90° operation.
Fine adjustment of the stop screws position is possible within a limit
of ± 2° maximum.
5
English
Travel limit switches description and function:
The cams operating the limit switches are on a cylindrical block which does not require any disas-
sembly. Each cam can be set independently of the others. The white and black cams are for OPEN
and CLOSE travel limit switches. The other cams actuate additional limit switches (Example : For
signalling).
How to operate the cams:
a) Put a screwdriver in the slot of the button encircled by the same color as the cam to be set,
b) Press lightly to disengage the cam of locked position,
c) By turning the screwdriver rotate the cam to the position in which it can trip the limit switch,
d) Remove screwdriver and ensure that the button has come back to its original position, thus
locking the cam in chosen place.
Procedure of mechanical stops and travel limit switches setting:
a) Loosen stop screws by 2 turns.
b) Manually drive the valve to the closed position. If mechanical stops
are reached before the valve closing is completed, it means that the
2° maximum adjustment tolerance has been exceeded ; do not try
to go beyond this limit.
c) Set the cam of the «CLOSED» travel limit switch.
d) Turn stop screws clockwise to the mechanical contact, reloosen 1.5
turn, and secure by lock nut.
Proceed in the same way in open position.
Perform complete electrical valve opening and closing operations.
It is mandatory that the motor stops on the travel limit switch and
not on the mechanical stop.
4.3 POSITION FEEDBACK POTENTIOMETER
(EZxxxx FA XX 123 A1 only)
The potentiometer used for actuator signal feedback is driven by the travel cam block system.
0% position corresponds to a closed valve. 100% to an open valve.
Circuit board mounted version
To mount the potentiometer device on the switch plate, clip it without
the position indicator on the camblock and screw it on the support
column. Screw the position indicator back.
Setting of potentiometer zero is achieved thanks to the «0% postion»
screw.
Drive the actuator to the closed position.
Resistance value is measured between terminals 16 and 17.
Hold the pinion located just under the plate with the «0% position»
marking while driving the potentiometer screw. Adjust the potentiome-
ter so that the resistance value exceeds 0 Ohm and regularly increases
then turn backwards to reach a value as close to 0 Ohm as possible.
Drive the actuator to the open position and write down the resistance
value corresponding to the 100% position.
Come back to the closed position and check that, for the 0% position,
the resistance shows a close to zero repeatable value.
6
On support column mounted version (EZ4 to EZ15 actuactors)
To mount the potentiometer device, screw the support column on the mounting plate and engage the driving
pinion into the camblock wheel.
To adjust the potentiometer resistance value, loosen the nut with the
wrench and rotate potentiometer until the signal requested is archieved.
To set the 0%, drive the actuator to the closed position.
Resistance value is measured between terminals 16 and 17.
Rotate the potentiometer so that the resistance value exceeds 0 Ohm
and regularly increases then turn backwards to reach a value as close
to 0 Ohm as possible.
Retighten nut after setting.
Drive the actuator to the OPEN position and write down the resistance value corresponding to the
100% position. Come back to the closed position and check that, for the 0% position, the resistance
shows a close to zero repeatable value.
Signal inversion:
To inverse the signal variation direction, invert potentiometer wires on the actuator terminal board
(e.g. for a connection on 16/17/18, invert 16 and 18).
4.4 «TAM» POSITION TRANSMITTER
(EZxxxx FA XX 123 A2 only)
The TAM transmitter delivers a 4 to 20 mA signal linearly proportional
to the angular position of the valve.
Electric connections
Refer to the wiring diagram supplied with the actuator.
FIltered or stabilised power supply should be provided within the 12
to 32 VDC range. Maximum admissible ohmic load values are given in
the table :
Energy Supply
DC (VOLT)
Max. admissible
load Ohm
12 150
24 750
30 1050
7
English
Signal direction inversion
The TAM transmitter, when supplied with a standard actuator, provides a signal that rise from close
position to open position, the standard opening direction being counter-clockwise.
If an opposite signal variation is required, simply move 2 jumpers on the board near the potentiometer.
Direct signal : jumpers on 1-3 and 2-4
Reversed signal : jumpers on 1-2 and 3-4
Settings
Connect a milliampermeter at the place of burden.
- Always start by adjusting the 4mA.
- Drive actuator to the position corresponding to the 4 mA (closed
position),
- Hold the pinion located just under the plate with the «0% position»
marking while driving the potentiometer screw. Adjust the poten-
tiometer so that the output current reaches a minimum value. Turn
backwards until the current value regularly increases then turn
backwards again and stop as soon as the minimum value determined
here above has been reached. The potentiometer is then positioned
at the very beginning of its track.
- Then, use the TAM adjustment screw marked as «0/4mA» to adjust
the current to a value as close to the 4 mA as possible.
- Drive actuator to the position corresponding to the 20 mA (open position),
- Turn the screw marked «20mA» in order to read exactly 20 mA on the milliampermeter.
- Come back to the closed position and check that, for the 0% position, the signal current shows
a close to 4 mA and repeatable value.
4.5 AUXILIAIRY CONTROL SWITCHES
The OPEN and CLOSED signalling can be managed separately by two separated control switches.
These switches are actuated by brown and grey cams.
They can be connected through terminals 20 to 25 as follow :
4.6 HEATING RESISTOR
Each actuator includes a heating resistor. As soon as the actuator is installed in the field, it is
recommanded du supply the resistor to prevent condensation.
4.7 CAUTION
Replace covers immediately after start-up and make sure that their seals are clean. Never fail
to replace the protection covers. If water ever enters, dry thoroughly before replacing covers.

6 TORQUE LIMITER
EZ25 to EZ1000 actuators are equipped with a torque limiter.
IMPORTANT :
With EZ SWITCH, the Torque limiter give pulse contact at the maximum
possible torque.
After stopping the motor, the information is not mechanically memo-
rized. Therefore store information via an self-maintained relay (see
example of cable at the end of document).
On EZ LOGIC, the torque is measured by a strain gauge. The torque
information memorized by the control board.
7 MAINTENANCE AND STORAGE INSTRUCTIONS
Maintenance
If actuators is correctly mounted and sealed, no special maintenance is required. Check once a year
function of motor and make sure that switch compartment is condensation free. If environment is
humid, we recommend to connect the anti-condensation heater resistance, thus protecting electric
parts from alteration (On EZ LOGIC, heater resistance function is included in the power board).
Actuators are lubricated for lifetime.
Storage
The actuators includes electric equipment as well as grease lubricated gear stages. In spite of the
weatherproof enclosure, oxydising, jamming and other alterations are possible if actuator is not
correctly stored.
Actuator stored in a warehouse
a) The actuators should be stored under shelter, in a clean, dry place and protected from successive
changes in temperature. Avoid storage on the floor.
b) Supply the heating resistor in the case of presence of moisture.
c) Check that plastic plugs of the cable entries are well in place. Ensure the tightness of covers and
enclosures containing electrical components.
Actuator installed but waiting for electrical connection
If there is a long wait between the actuator mounting and electrical connection works:
a) Check the proper sealing of the cable-glands electrical boxes,
b) Cover the motor with plastic film,
c) Supply the heating resistor in the case of presence of moisture.
Storage of actuators equipped with electronic components
Long term storage of electronic components which are not in service increases the malfunction risk. This
practice is therefore highly unadvisable.
Control after storage
a) Check visually the electrical components,,
b) Operate manually the switches to check the proper mechanical work,
c) Operate apparatus manually,
d) Carry out the commissioning of the actuator according to the instructions attached to each device
